Answer: width = 10 ft
Step-by-step explanation:
Area = length × width
Let l be length and w be width
l = w + 4 ........equation (1)
From above formula
140 = l × w. ........equation (2)
Substitute equation (1) into equation (2)
140 = (w+4) × w
w^2 + 4w= 140
w^2 + 4w - 140= 0
By factorization method
(w+14)(w-10)= 0
w=-14 or w= 10
So now width is 10 ft
From equation(1)
l=w+4
l= 10+4
l= 14 ft
Width = 10 ft and length = 14 ft
I assume you mean 9+52,
If so you can add the 9 and the 2 together:
9+2 = 11
Then you can add the 11 on to the 50 to get the final answer:
50+11 = 61
Hope this helps! :)

Answer: 2z^3</h3>
====================================================
Explanation:
The GCF of the coefficients {6, -42, 14} is 2 as it is the largest factor found in each of the three values.
----------
For the variable portions, we can
- write z^5 as z^3*z^2
- write z^4 as z^3*z^1
- write z^3 as z^3*1
Each time we see z^3 show up, so this is the largest common factor among the three variable terms.
----------
The two results we got were 2 and z^3
Putting the two results together, we end up with the overall GCF of 2z^3
Let the amount saved by the brother that has less savings be x, then the savings of the other brother is x + 15.
Since their total savings is 55, then
x + x + 15 = 55
2x + 15 = 55
2x = 55 - 15 = 40
x = 40 / 2 = 20
Therefore, one person saved 20 and the other saved 20 + 15 = 35.
